Pass-Through Picker System for a Data Storage Library

      A simple-mechanism design concept for a pass-through picker is
disclosed.  This design minimizes the number of motors used to
perform multi-independent functional operations.

The picker design of this invention, as illustrated in Fig. 1,
comprises:

o   A gripper 1 which moves up and down along the cartridge
    magazine/drive column 2 in the Z direction.  The gripper 1 can be
    rotated about the Y axis for cartridge-flipping action.

o   Four sets of belt/pulley rollers 3 to move the cartridge along
    the gripper 1 in the Y direction.  The rollers 3 are independent
    from each other and mounted onto the sides of the gripper 1.

o   Four sets of rollers 4 mounted on the sides of the opening of the
    cartridge storage slots 5 of the cartridge magazines.

o   Two drive rollers 6 which can be engaged and disengaged from
    rollers 3 and rollers 4 by a control means 7.  The rollers 6 and
    the control means 7 ride along the Z axis together with the
    gripper 1.

o   Detaining means 8 at each of the openings of the gripper and the
    cartridge storage slots.  The detaining means is to stop and lock
    the cartridge in proper position.  The detaining means 8 at
    specific openings are unlocked by engaging the roller 6 to the
    rollers 3 and 4 at the openings.

      To remove or insert a cartridge from or to a cartridge storage
slot, the control means 7 engages the drive roller 6 to the rollers 3
and 4 at the opening of the storage slot and rotates in appropriate
direction.  All of the rollers 6 must be in disengaging position for
cartridge-flipping action.

      For double gripper application, it requires two gripper
assemblies and two sets of drive roller 6 stacking on top of each
other.  Only one control means is needed.  One input is re...
